An embedder can extend the SQL dialect with its own statements, but has had nowhere to say what a statement *is*: its grammar, the label it reports to an audit log, and the access it needs are three separate facts, and describing them separately means a host ends up with parallel downcast chains that must be kept in step by hand. Adding a statement to only two of the three is a silent gap rather than a compile error. `lancedb::sql` gains the seam that keeps them together: - `CustomSqlHandler` contributes a grammar; `route_custom_sql` picks the one that owns a statement and leaves the rest to DataFusion. - `SqlStatement` pairs a planned node with its audit label and the `AccessRequirement`s it needs. The vocabulary names what is reached for -- read, write, own, create, database, namespace, system -- rather than a privilege, so no access-control model has to live in the dialect. - `StatementRegistry` holds both, with the consultation order it is given. Registration is front-insertion so an extension can get ahead of a catch-all that would otherwise swallow its keyword. - `WriteObserver` reports a committed write without the statement knowing how its host represents that. - `DmlResult` carries what a DML statement did as a one-row batch. The feature adds no dependency that is not already required, so it is on by default; the flag is there so an embedder that does not want the surface can opt out.
